Patent number: 6033516Abstract: In the production of an anticopy film serving for covering documents against copying, opaque, strip-like coverings are applied by printing to the individual layers of a transparent, multilayer film in a mutually offset arrangement in such a way that the film appears opaque in the plan view, but transparent in an inclined viewing direction. To this end, a film web is printed with the coverings in sections corresponding to the layers, and the sections are subsequently folded over to give the layers.Type: GrantFiled: July 14, 1994Date of Patent: March 7, 2000Assignee: Emtec Magnetics GmbHInventors: Helmut Steininger, Peter Heilmann, Michael Willis

Patent number: 5795643Abstract: An anticopying film or layer consists of a film or of a layer of transparent material having a large number of completely or partially nontransparent regions which are arranged distances apart and whose planes are arranged in about the same predetermined position relative to the surfaces of the film or of the layer so that, from a predetermined viewing angle onto the surfaces of the anticopying film, the latter is essentially transparent. The regions consist at least partially of photosensitive material which is converted by the action of radiation into nontransparent or reflecting material, it also being possible to provide, in the transparent plastics material, furrows or grooves in which the photosensitive material is present.Type: GrantFiled: February 13, 1995Date of Patent: August 18, 1998Assignee: BASF Magnetics GmbHInventors: Helmut Steininger, Peter Heilmann, Peter Hewkin

Patent number: 5763074Abstract: The heat sealing film and a magnetic transfer strip contain an adhesive layer comprising thermoplastic, immiscible binder components. One component is spherical, amorphous and embedded in finely distributed form in a homogeneous layer of the other, highly crystalline components in such a way that the spherical component protrudes hemispherically from the layer. The spherical binder is a glassy solid up to at least 60.degree. C. and above 80.degree. C. is plastically deformable. The hemispheres protruding from the adhesive layer produce a uniform, fine roughness of the surface. Both heat sealing film and magnetic transfer strip are nonblocking up to at least 60.degree. C. and heat-sealable at temperatures greater than 80.degree. C. The adhesive layer imparts to a magnetic recording medium a uniform thickness of the adhesive joint and a permanent, temperature-resistant adhesive force.Type: GrantFiled: August 13, 1996Date of Patent: June 9, 1998Assignee: BASF Magnetics GmbHInventors: Albert Kohl, Karl Heinz Romer, Werner Latzel, Peter Heilmann, Michael Hitzfeld

Patent number: 5728449Abstract: An anti-copy film or layer for originals or documents comprises according to the invention transparent film material having a multiplicity of at least partially opaque and possibly reflective areas arranged at distances from one another which are arranged as screens on the film surfaces essentially in horizontal planes, in particular parallel to one another, but offset, so that information on an original lying under this film or layer is masked in an approximately vertical viewing direction and is visible in the direction of a predefined viewing angle. Expedient production methods enable the use of photographic techniques.Type: GrantFiled: February 13, 1995Date of Patent: March 17, 1998Assignee: EMTEC Magnetics GmbHInventors: Helmut Steininger, Peter Heilmann, Peter Hewkin

Patent number: 5585139Abstract: The magnetic recording medium consists essentially of a polymeric substrate, a coherent, magnetic thin metal film applied to the surface of the substrate by a PVD method and, if required, a protective layer formed on the thin metal film. In order to achieve a large residual induction component in the plane of the film, in particular high residual induction in the transverse direction, the thin metal film contains a noble gas or noble gas mixture, preferably argon. During the coating of the polymeric substrate with the magnetic metal or with the magnetic alloy, the noble gas is fed directly and preferably tangentially to the substrate surface at a specific noble gas flow of from 1.0.multidot.10.sup.4 to 6.0.multidot.10.sup.4. In the plane of the thin metal film, the ratio of residual induction in the longitudinal direction to that in the transverse direction is from about 0.9 to about 1.8.Type: GrantFiled: December 12, 1994Date of Patent: December 17, 1996Assignee: BASF Magnetics GmbHInventors: Helmut Steininger, Peter Heilmann

Patent number: 5569522Abstract: An anticopying film (2) for covering documents (1) appears opaque in vertical plan view (5) as a result of total reflection for protection against copying and appears transparent in the oblique viewing direction (6), the film having an irregular sawtooth structure (3). This makes it virtually impossible to produce an identical second film with the aid of which, by placing said second film on top, the effect of the anticopying film (2) might be eliminated.Type: GrantFiled: August 24, 1994Date of Patent: October 29, 1996Assignee: BASF Magnetics GmbHInventors: Helmut Steininger, Alan Green, Michel Munch, Peter Heilmann

Patent number: 5490476Abstract: An apparatus for checking deep-frozen food, which irreversibly indicates if an additional storage temperature has been exceeded, is described. A flat plastic bag having transparent walls, into which eutectic mixture having a liquid/solid phase transition in the range from 0.degree. to -50.degree. C. has been introduced, together with a magnetic dispersion consisting of finely divided magnetic pigments, has a heat-conducting connection to the material to be frozen. A magnetic stripe which contains a magnetically recorded pattern and which remains connected to the bag until the indicating apparatus together with the material to be frozen has been cooled below the limiting temperature is stuck to the bag. The magnetic stripe is then removed. If the permissible limiting temperature is exceeded, the optically or magnetically readable structure produced by the magnetic stripe in the indicator bag is eliminated, permitting easy checking of the deep-frozen food.Type: GrantFiled: August 8, 1994Date of Patent: February 13, 1996Assignee: BASF Magnetics GmbHInventors: Ronald J. Veitch, Helmut Jakusch, Peter Heilmann
